ESU LT User Manual

ESU LT Interfaces

The ESU LT is equipped with four interfaces:

•

E1 Network interface per ITU G.703

•

Nx56/64 high-speed, multi-protocol serial interface

•

Control input (EIA-232)/Chain port input

•

Chain port output

See Figure 2-2 and the following descriptions in this section.

Figure 2-2. ESU LT Interfaces

Network Interface (NI)

The Network Interface (NI) port provides the connection to the E1.
This port complies with the applicable ANSI and CCITT standards.
The 120

Ω

DB-15 interface (adapter provided) may be used for the

NI. For more information, see

Appendix B, Pinouts

on page 69.

Network Test Interface

The MON test jack provides a bridged access jack for non-intrusive
monitoring of the incoming E1.

Nx56/64 Serial Interface

The Nx56/64 provides a serial interface that operates from
56 kbps to 2.048 Mbps. The Nx56/64 can be configured as a V.35,
V.36, EIA-530, or V.11 electrical interface through the front panel
menus.
